Doctrine 1.2: How can I prohibit one-to-many opposition to both sides?

Question

Is there a way to prevent the Doctrine from assigning a one-to-one relationship on both sides? Ive tried to move the definition from one side to the other and use its own side, but still puts a restriction on both tables. when I want the parent table to have a constraint - that is. its possible for a parent to not have an associated child.

For example, the following sql schema is essentially:

CREATE TABLE `parent_table` (
  `child_id` varchar(50) NOT NULL,
  `id` integer UNSIGNED NOT NULL auto_increment,
  PRIMARY KEY (`id`)
);

CREATE TABLE `child_table` (
  `id` integer UNSIGNED NOT NULL auto_increment,
  `child_id` varchar(50) NOT NULL,
  PRIMARY KEY (`id`),
  UNIQUE KEY (`child_id`),
  CONSTRAINT `parent_table_child_id_FK_child_table_child_id`
    FOREIGN KEY (`child_id`)
    REFERENCES `parent_table` (`child_id`)
);

However, I get something like this:

CREATE TABLE `parent_table` (
  `child_id` varchar(50) NOT NULL,
  `id` integer UNSIGNED NOT NULL auto_increment,
  PRIMARY KEY (`id`),
  CONSTRAINT `child_table_child_id_FK_parent_table_child_id`
    FOREIGN KEY (`child_id`)
    REFERENCES `child_table` (`child_id`)
);

CREATE TABLE `child_table` (
  `id` integer UNSIGNED NOT NULL auto_increment,
  `child_id` varchar(50) NOT NULL,
  PRIMARY KEY (`id`),
  UNIQUE KEY (`child_id`),
  CONSTRAINT `parent_table_child_id_FK_child_table_child_id`
    FOREIGN KEY (`child_id`)
    REFERENCES `parent_table` (`child_id`)
);

/* @var $address Address */
$address = $form->getObject();

// the null object is here the "address position", let change it state
$address->getAddressPosition()->state(Doctrine_Record::STATE_CLEAN);

// now we can save the address and doctrine won't insert the null object
$address = $form->save();
